This is exactly what I just did and it's been great so far. The battery life isn't spectacular for todays standards, but it lasts longer than my 2012 rMBP 15" does now. Quick, light (way lighter than the MBP) and has been fun to draw on. Getting use to windows again takes a bit of time, but with the new Bash integration, my workflow is just about the same.

Well, compared to a smartphone or an ipad. It's a normal wake up time for a laptop.
